Solve the following inequality. 4x-1> -9
Radda [10]
The answer is x>-2 first you just move the -1 by adding 1 to both sides. Then you get 4x>-8 then you must isolate the x by dividing the 4 on both sides. After you divide it you will have just x on one side of the inequality and -2 on the other side. this will leave you with the inequality x>-2

Which of the following is the solution to 4|x+2|>16
marusya05 [52]

Answer:

x < - 6 or x > 6

Step-by-step explanation:

Inequalities of the type | x | > a, always have solutions in the form

x < - a or x > a

given 4| x + 2 | > 16 ( divide both sides by 4 )

| x + 2 | > 4 ← in the above form, hence

x + 2 < - 4 or x + 2 > 4 ( subtract 2 from both sides of both inequalities )

x < - 6 or x > 6 ← solution

Needing some help please!!
lina2011 [118]

Answer:

a. 2

b. 3

c. 3x^2+9x+15

d. 257

Step-by-step explanation:

f(x)=x^{2}+1 \\g(x)=3x+4 \\

When a function is written like that the value in the parenthesis is what you use to replace the x inside the expression.

a. f(-1) means the value of function "f" when x = -1

f(-1)=(-1)^{2}+1=1+1=2

b. "f" when x = -2 + "g" when x = -2

f(-2)+g(-2)=(-2)^{2}+1+3(-2)+4=3

c. multiply for 3 each function

3f(x)+3g(x)=3(x^{2}+1)+3(3x+4)=3x^{2}+9x+15

d. "g" when x = 4 then "f" when x = g(4)

g(4)=3(4)+4= 16\\f(g(4))=f(16)=16^{2}+1 = 257
